Work on the replacement of the 100-year old Catawba Bridge over Miry Run on Route 559, Somers Point-Mays Landing Road, between Egg Harbor and Hamilton townships is underway with a full detour in place as of October 5 through May 2016.
Construction will result in a new bridge and roadway built well above the 100-year flood elevation, while complying with the 5-foot under-clearance required by the federal regulations that govern Miry Run within the Great Egg Harbor River Wild and Scenic River System.
Work through November will include the demolition of the existing single-span, concrete encased steel stringer structure and installation of temporary and permanent sheeting. That work will be followed by soil excavating and installation of test piles, and procurement of production piles in December.
As of January 2016 work is scheduled to include the installation of production piles, and forming and pouring the concrete abutments. After that will come the installation of the arch bridge structure and headwalls as well as retaining walls, pipes and inlets. At this time the approach roadways will also be milled.
During March and April, layers of structural fill and geogrid will be installed for the roadway subgrade and concrete will be poured for the parapets. Bridge rail and roadway guiderails will also be installed. The roadway will be paved and striped, and topsoil and seed will be spread. Upon completion the detour will be removed and the roadway will reopen to traffic.
After a 90-day period, the surface course will be milled and paved to account for any settlement. The new bridge will remain open during this period.
County officials appreciate the public’s cooperation during construction and urge motorists to drive cautiously along designated detour routes that may not typically experience increased volume.
